       7. The cloth article as set forth in  claim 1 , wherein the varistor material is particulate and the ferrite material is coated onto the varistor material particulate. 
     
     
       8. The cloth article as set forth in  claim 7 , wherein the size of the particles of the varistor material is approximately 50 nm to 50 micron in diameter and the thickness of the ferrite material that is coated onto the varistor material particle is approximately 5 nm-100 nm. 
     
     
       9. The cloth article as set forth in  claim 1 , wherein at least one of the varistor material and the ferrite material is within particles, the particles are secured relative to the conductive fibers within the cloth article. 
     
     
       10. The cloth article as set forth in  claim 9 , wherein the particles are secured within a polymer material adhered with the conductive fibers within the cloth article. 
     
     
       11. The cloth article as set forth in  claim 1 , wherein the conductive fibers provide a protection from electromagnetic energy over a first range of frequencies of electromagnetic energy, the varistor material provides a protection from electromagnetic energy over a second range of frequencies of electromagnetic energy, and the ferrite material provides a protection from electromagnetic energy over a third range of frequencies of electromagnetic energy, and the first, second and third ranges of frequencies being different from each other. 
     
     
       12. The cloth article as set forth in  claim 1 , wherein the cloth article is an article of clothing. 
     
     
       13. The cloth article as set forth in  claim 1 , wherein the cloth article is a sheet material. 
     
     
       14. The cloth article as set forth in  claim 1 , wherein the cloth article is flexible. 
     
     
       15. The cloth article as set forth in  claim 1 , wherein the provided protection is for electromagnetic energy including frequencies in the range of approximately 50 Hz to approximately 300 GHz. 
     
     
       16. A method of providing cloth article that can provide protection from electromagnetic energy, the method including:
 providing conductive fibers extending within the cloth article; 
 providing varistor material dispersed and secured within the cloth article; and 
 providing ferrite material dispersed and secured within the cloth article. 
 
     
     
       17. A method as set forth in  claim 16 , wherein the step of providing the conductive fibers includes providing carbon fibers as the conductive fibers. 
     
     
       18. A method as set forth in  claim 16 , wherein the step of providing varistor material includes providing the varistor material within particles. 
     
     
       19. A method as set forth in  claim 16 , wherein the step of providing ferrite material includes providing the ferrite material within particles.
